FLYING-MACHINE Specification of Letters Patent.

.To all 'wh-om t may concern:

Be it `known that I, ALEXIS RoGEsTvENsKY, a subject of the Emperor ofRussia, residing at Moscow, Russia, have invented certain new and usefulImprovements in Flying-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tolet-ters or figures of reference marked thereon, which form a part ofthis application. 1 1

The invention relates to flying machines heavier than air, and has forits object-the construction and 'arrangement thereof as will behereinafter more particularly described and claimed. r

Referring to the drawings in which like parts' are similarlydesignated-Figure 1 is a side elevation of my iying machine; Fig. 2 is afront elevation thereof, the left-wing being broken awayat its end; Fig.3 is a plan view of Fig. 2; Fig. 4 is a view similar to Fig. 3 inanother position; Fig. 5 -is a view similar to Fig. 1 of the machine asit Y is about to alight.

The machine comprisesa body portion'or frame, a, b, c, d, e, f, whoselower members. d, e, f, are designed to rest on the ground, similar tothe runners of a sled. On each side of the body portion are provided .apair of equally inclined guides g. Cooperating with the guides g 1s aplatform h movable with respect to the body portion on the guides g.This platform has its forward and rear trunnions or pins z"- extendinginto] the slots formed between the guides g. Below the platform h isafrodi held by braces 2, and this rod is connected to a similar rod 2,between the members c, c of the body, byy elastic connections, rubberropes c, that permit the platform it to assume the dotted line positionFig. 1, with respect to the body. In lieu of the rubber ropes k, I mayuse springs, pneumatic or other devices effecting a simi- Ilar function.

The flying mechanism is mounted on a turn-table Z on` the .platform L,and said turn-table Z has a lpair of lateral triangular frames m in theuppenparts of which are mounted a 'casing o on trunnions m. Theframe-work of the wings or planes s is se- Application ed September 2,1909. Serial No. 515,840.

cured to the sides of the casing 0. Through the casing o in thedirection D-E .extends the propeller shaft n having on each end thereofa screw-propeller p. The planes s with the casing o and propellers p maybe rotated to inclined positions on the trunnions m.

On the turn-table Z are mounted the motor 15, the pilots seat y andlevers and pedals v for controlling and operating the flying machine.

In Fig. 2 I have shown the fabric of one of the planes, the upperplane,as being arranged to be reefed at The planes s and the uprights 1"connecting them are fastened together" by Wires z.

In order to start the machine .it is necessary 'to move the platform h(Fig. 1) from the right hand end of the body, full line position, to theleft hand end of the body, dotted line position, along the guides g,

thus lowering the platform h and the mechanism carried thereby. Duringthis movement from the end B toward the' end A, theelastic members orrubber ropes la are stretched and so held by locking the platform in itsnew or starting position by suitable mechanism, not shown. The casing 0is now inclined parallel with the guides g and the rudders g at thesides of theframe m' below the casingo are also inclined. The pilot thenVassumes his seat on .the platform at y and actuates the .motors bymeans ofy pedals or levers 'v of any suitable arrangement. Thetransmission from the motor t to the propeller shaft is not shown, asany suitable arrangementv may be-used for the purpose. When thepropellers p have assumed a suitable speed the pilot releases theplatform h by means of one of the levers or pedals o. The ropes cvorequivalent resilient devices then contract, starting the platform andflying mechanism suddenly up l the inclines g aided by the propellers p,ending in the full line position Fig. 1, with a shock, due to theinertia of the moving parts assisted by the propellers andthe rubberropes k, so that the entire machine including the body, whichv iscomparatively light, rises from the ground, after which the planes andpropellers maintainit inthe air. After the machine Ahas risen the bodyand platform are turned relatively to the superstructure one-half turn,eitherA by sultable automatic mechanism or by the pilot himself, to thefull line position shown in' Fig. 5, thu maintaining the direction offlight of the superstructure on the turn-table Z. The platform h ispreferably but not necessarily locked in its position relatively to thebody. On the descent the body first strikes the ground, the platform z.becomes unlatched by the mertia, and the platform descends to the dottedline position Fig. 5, stretching the ropes lc, which act asshockabsorbers, and assumes its initial position with relation to thebody ready for the next flight, the said platform l1, being locked orlatched in this position. It is now only necessary to turn theturn-table Z a half turn to bring `the machine to the dotted lineposition Fig. l, ready for the next flight.

The construction and arrangement of the platform vrelatively to the bodypermits the starting of the machine without a preliminary I'un along theground.

I claim- 1. The combination withl a body and inclined parallel guidesthereon; of a member slidable in the guides and maintained parallel tothe body, elastic means between the member and body which are contractedupon starting and distended upon alightlng, and flying mechanism carriedby the member.

2. The combination with a body and inclined guides thereon; of a memberslidable in the guides, resilient means between the member and body, aturn-table on the member and flying mechanism on the turn-table.

In testimony whereof, I have signed my name to this specifica-tion inthe presence of two subscribingl witnesses. l
